I need to build an SHF transmitter / receiver that has the range of 8-12 GHZ for communication satellite communication … Super high frequency (SHF) is the ITU designation for radio frequencies (RF) in the range between 3 and 30 gigahertz (GHz). This band of frequencies is also known as the centimetre band or centimetre wave as the wavelengths range from one to ten centimetres. These frequencies fall within the microwave band, so … See more Microwaves propagate solely by line of sight; because of the small refraction due to their short wavelength, the groundwave and ionospheric reflection (skywave or "skip" propagation) seen with lower frequency radio waves do not … See more The wavelength of SHF waves is short enough that efficient transmitting antennas are small enough to be conveniently mounted on handheld devices, so these frequencies are … See more • Knife-edge effect • Microwave burn See more SHF frequencies occupy a "sweet spot" in the radio spectrum which is currently being exploited by many new radio services. They are the lowest frequency band where radio waves can be directed in narrow beams by conveniently sized antennas so they do not … See more • Tomislav Stimac, "Definition of frequency bands (VLF, ELF... etc.)".
